PFERD was recently featured in the August 2018 edition of FAB Shop Magazine Direct. The article interviews PFERD brush product manager Imre Karetka, who speaks about the importance of deburring, the various deburring options available, and the role of deburring and surface conditioning in automation, which maximizes efficiency in industries that deal with high production volumes on a daily basis, particularly the automotive industry.
In machining terminology, a “burr” refers to a rough edge or ridge on a metal workpiece that remains after the action of a cutting tool or grinding machine. Typically unavoidable byproducts of the machining process, burrs can be problematic if left on the final product. Deburring, as its name suggests, is the process by which burrs are removed, ensuring a smooth and consistent surface finish.
Haven’t read the article yet? Below, we’ll provide an overview of the key takeaways and offer insight into some of PFERD’s deburring solutions.
The Importance of Deburring
Few industries impose stricter safety demands than the automotive industry. Automobile parts and components must be designed to meet stringent specifications and tight tolerances; deburring is a critical manufacturing step to ensure adherence to these requirements.
Internal automobile parts are constantly moving to keep a vehicle functioning smoothly. As Mr. Karetka points out in the FAB Shop article, burrs left behind during manufacturing can break off during operation, resulting in metal flakes flowing within the vehicle’s internal mechanisms. Foreign objects in the transmission, for example, will negatively affect the vehicle’s overall performance and present several safety hazards.
Mr. Karetka also discussed deburring tools as a means of automotive component surface conditioning, such as for camshafts. Bearings, called journals, must be properly finished to facilitate the flow of lubricant onto the camshaft. Improper surface preparation results in lack of lubrication and accelerated wear of metal parts, which causes overheating and seizing of the engine.
Creating Customized Deburring Solutions
Primarily focusing on deburring applications in automation, the article noted that many industries, especially automotive, regularly mass produce parts and components as part of their daily operations. This production process, however, can present unique challenges.
First, conventional manual deburring methods are often inadequate due to time constraints and increased cost of manual labor. Second, space constraints in some facilities can limit the size of brushes that can be used in automated deburring and surface preparation techniques.
To overcome these challenges, PFERD partners with industrial CNC and robotic OEMs to develop customized deburring solutions for specific applications. Our team also configures the grit and wire sizes, increasing them as required to maintain deburring efficiency while minimizing equipment and tool size.
Tackling Deburring Challenges in Automation
At PFERD, we understand that unique situations call for different deburring solutions. To address these different use cases, we offer a range of automated solutions to meet the requirements of almost any industry including:
- Abrasive brushes –Available with various abrasive materials including aluminum oxide, silicon carbide and ceramic oxide, M-BRAD® brushes are suitable for surface conditioning on a variety of materials including wood, glass, and most metals and alloys.
- Carbide burrs – Known in the industry for precision, consistency, and concentricity, our carbide burrs are designed for deburring machined holes in metals of virtually any composition or strength. A range of general-purpose burs – as well as material and application specific burs – gives users choices for the optimum solution for their specific application
With more than 200 years of experience in the business, PFERD has established itself as an industry leader providing single-source cutting, grinding, and finishing solutions for many specialty applications. In addition to our standard catalog offering, our team of engineers and technical staff has the experience and expertise to develop customized deburring and surface conditioning solutions to meet customer project-specific requirements. We work closely with clients at every stage of the design process to ensure that our products exceed expectations.
